Abstract

Nonlinear magnetoelectric effect(NME) in alkali atomic vapor has applications in precision magnetometry in the radio-frequency domain. We report the application of the NME in alkali atomic vapors for projective measurement of medium-frequency (MF) magnetic fields in a circular basis with an extinction ratio up to 500:1 . Utilizing a longitudinal static magnetic field, we demonstrate a high-sensitivity technique for characterizing the ellipticity of radio-frequency (RF) magnetic fields which can in turn be used for phase sensitive detection in mid frequency communication. Additionally, we demonstrate the conversion of binary phase shift keyed RF magnetic fields into amplitude modulation of generated optical fields, a versatile receiver for communication using the medium frequency band.

利用磁电效应的可重构圆极化中频原子接收器

碱原子蒸汽中的非线性磁电效应（NME）可应用于射频领域的精密磁测量。我们报告了碱原子蒸汽中的非线性磁电效应在圆基中频（MF）磁场投射测量中的应用，消光比高达 500:1。利用纵向静态磁场，我们展示了表征射频（RF）磁场椭圆度的高灵敏度技术，该技术可用于中频通信中的相敏探测。此外，我们还演示了将二进制相移键控射频磁场转换为振幅调制产生的光场，这是一种用于中频段通信的多功能接收器。
